Catherine Dubourdieu receives ERC Advanced Grant
Prof. Dr. Catherine Dubourdieu heads the Institute “Functional Oxides for Energy-Efficient Information Technology” at HZB and is Professor at the Physical and Theoretical Chemistry division at Freie Universität Berlin. The physicist and materials scientist specialises in nanometre-sized functional oxides and their applications in information technologies. She has now been awarded a prestigious ERC Advanced Grant for her research project “LUCIOLE”, which aims at combining ferroelectric polar textures with conventional silicon technologies.
With its ERC Advanced Grant format, the European Research Council enables outstanding scientists to conduct pioneering and groundbreaking high-risk research. An ERC Advanced Grant is considered one of the highest awards for experienced researchers.
The project LUCIOLE focuses on ferroelectric nanometer-size oxides, which can host exotic polar textures such as vortices or skyrmions. With a wealth of potential emergent properties, whirling topological polar nanodomains could lead to novel devices, for example ultra-compact memories that store more than a terabyte per square inch. “We want to pave the way to future low power nanoelectronics based on topological defects” says Catherine Dubourdieu.
Monolithically integrated polar textures on silicon will be created and investigated on a nanoscale with state-of-the-art microscopy and spectroscopy techniques. These engineered polarization patterns will be embedded into ultra-scaled devices to study their manipulation and dynamics under electric field.
"We have known about the phenomenon of ferroelectricity for a good hundred years. But it is only in recent years that exotic polar textures have been unveiled. This opens up exciting possibilities for revolutionary new materials and devices. This is definitely the best time to be at the forefront of this field of research," says Dubourdieu.
